feat: Add initial deployment setup for OTSSignsOrchestrator

- Create index.html for the web application interface.
- Implement deploy.sh script for building and deploying the application to a Docker Swarm manager.
- Add docker-compose.yml for defining application and PostgreSQL service configurations.
